Washing and drying a feather duvet

[Limth]

Because my life is a 24-hour roller-coaster of excitement, I'm (over)thinking about how to wash my feather duvet. I've been Googling but I want to talk to real people. And MN is full of real people.
I have a couple of questions, if anyone has the time to answer, please:

a. Although the label says to wash in a large capacity launderette machine, I'm confident it'll fit in my home machine. There's nothing special about launderette machines aside from them being bigger, right? I'm not going to ruin the duvet if I wash it at home am I? Is it ok to wash in a home washing machine?

b. Is there anything special that I should use as detergent? I washing planning to use normal biological powder, some Napisan, and a dash of Zoflora. Is that all okay for washing feathers?

c. I'm worried it'll go all flat and limp and lumpy once its washed. I know the answer to this is to tumble dry with some tennis balls. But I don't have a tumble dryer, and I can't easily get to a launderette. If I line dry it, will it remain flat and limp and lumpy? And, if so, is there anything I can do at home without a dryer to get the volume back into it?

Thank you!

I was feather duvets at home. Make sure it actually fits in the machine. I just use normal washing powder or liquid but use less than usual.
usually I line dry until the end then tumble dry to fluff up but line drying only is fine. You will need to go outside and give it a shake and move round fairly often. Or you could line dry it then give a couple of goes at the laundrette or half an hour in a friends dryer. You have to stop the dyer and move the duvet round every 10 mins
It sounds a hassle but I’ve washed and tumble dried a duvet in 2 hours. I just use the quick wash

I used one of those huge washing machines and dryers that are outside some local shops to me. You need to make sure the feathers are completely dry or they can end up smelling funny.
Definitely tumble dry if you can rather than line dry.

Thanks both. I can't tumble dry - its not an option.

I'm ancient and have just done this for the first time! A 13.5.tog double feather and down into my 10kg washing machine. It didn't like the weight with the spin cycle so I lowered the spin cycle and it was all fine. Normal washing powder only ( don't use softeners anyway)
Our weather has been awful so it was line dried for a whole dry day and then over a bannister for another day. The one negative I've found is the duvet doesn't feel quite as warm now, no idea if that's a thing though

I've dried without a tumble drier and it's been fine, just make sure you have breezy dry weather and turn and shake it frequently, or somewhere airy indoors where you can turn and shake it easily. I once washed and left it in the bath spread out on clothes horse and chairs while we were away for the weekend and it was perfectly dry and fresh when we got back. It was summer though and an airy bathroom. I wash down jackets and pillows all the time and dry without a tumble drier, they fluff up fine.

Thank you everyone. I hadn't thought about how heavy the duvet would be for my home machine. That might be an issue.

I just send mine to the laundry gor a service wash. I'll just not be able to get it dry otherwise.

Do they collect and return to you?

Dry cleaners often have a duvet wash service

I don't know to be honest if they offer that as a service, I just drop it off on my way to work and pick up the next day usually. (I've only washed it 3 times....oops).

What do damp feathers smell like? I washed my pillows last summer, left and turned them in sunshine for hours and hours yet they smell faintly like unwashed hair. And yes, they're all double cased.
